High-Rate Mechanical Response and SEM Morphology of EX99 Gun Propellants
Abstract
Two lots of EX99 gun propellants from the Naval Surface Warfare Center (NSWC) were tested in uniaxial compression to an end strain of approx. 60%. The materials were preconditioned at test temperatures of 21 deg, 50 deg, and -20 deg C while at ambient pressure. The stress at failure, strain at failure, compressive modulus, failure modulus, incremental energy density (IED), and the fracture assessment values (FAV) were recorded for each test These materials were also evaluated for microstructure using a scanning electron microscope (SEM).
